To all whom t may cmi-cern:

Be it known th citizen of the United in the county of Dunn and Statehave invented certain new and Menomonie,

of 'Wisconsim useful Improvements l thevfollowing to be a full,description of the invention, able others skilled in the art do herebydeclare clear, and exact Vsuoli as will en to which it apper saine'.

This invention at l, VVILBUR A. Giiovnn, a States, residing at in GasBurners ;-and I tains to make and use the relates to a liquid fuel suolia burner having gas generating means therein. Such n burners are nowcommonly used in domestic stoves and ranges and also in connection withdomestic furnaces.

It is an object vide a burner of of vthis invention t-o provsimple andefficient con-l struction having a .series of burner tubes, a

portion or all of one time.

It is a further pro-vide a burner ,burner tubes, va abovek the burnerliquid fuel is pas brass filings.

provide a which-may be burned at object of the invention to having avplurality of generator tube ldisposedv tubes through which the sed,.which generator tubev divided metal such as invention toy having aplurality of tubes connected at their ends to supply conduits which areconnected to one side of amixing chamber, said mixing chamber beingconnected to a generatingtube disposed over which generating the burnertubes, tube is provided with a plurality of fine screens.

. These and other objects andl advantages of the .invention will befully set forth inthe following description made in connection with theaccompanying like reference characters parts throughout which, I

Figp is a view in side elevation of a ring used; Vand a f Fig. 6 is aview of a screen usedin the Referring to the drawings, a supply pipe 1is shown which will'be connected to an oil supply tank or means so thatoil will be fed thereto by gravity or pressure. Said pipe 1 is connectedby a suitable union member 2 to a generating tube 3 extendinghorizontally, which tube has disposed therein a considerable distancefrom the'member 2, a reduction union or nipple 4. A portion 3a of thegenerating tube 3 extends from the reduced end of the nipple 4 and islaterally' curved substantially in a semi-circle and connected to oneside of a inixingchamber 5, a set screw 6 holding the portion 3a inrareduced extension 5a 0f said mixing chamber. The nipple 4 has avshoulder formed therein and plurality of fine mesh screens 7 aredisposed in said nipple, said screens being spaced by small rings 8disposed therebetween.` The screen in one end abuts said the other endengages the end of the leg portion of generating tube y3 which holds thescreens in proper position. The screens 7 preferably are progressivelyof finer mesh toward the portion. 3a; The portion of the preferably isfilled with finely divided metal such as brass filings. rlhe portion 3ahas its lend which is'disposed Vin the mixing chamber 5 closed save 'fora small discharge opening 3b and said end also has disposed therein aplurality of nfine mesh screens 9 spaced by suitable spacing rings 10similar to the rings 8 already described. The mixing chamber 5, as shownin Fig. 3, comprises a hollow inember preferably of cast form having `adownwardly extending open-ended portion 5b. A

' conduit 11 extends from the side of mixing chamber 5 opposite theportion 3a, being held, in a projection 5c at one side of the mixingchamber a set screw 12. 1 The conduit 11 v is connected by an' elbow13to a T'member distance below the conduit 11'.` Pipesvor conduits 15and 16y extend, from the ends of T member 14 directions andhave theirends angles to extend which ends are in opposite bent substantially atright in nspaced parallel relation,

closed by suitable plugs 1'?l and connected by a p'late 18extending.therebetween, said plate being connected tothe plugs 1 7 byheaded screws 19. A small plateA or bracket 5 25 connects conduit 15 tothe union 2 and forms a support for the latter and pipe. .l.
